Topographic Features:

Brophy Model: Type D: Sedimentary-hosted, Volcanic-related Resource

Moeck-Beardsmore Play Type: CV-2a: Plutonic - Recent or Active Volcanism, CV-2b: Plutonic - Inactive Volcanism, CV-3: Extensional Domain"CV-2a: Plutonic - Recent or Active Volcanism, CV-2b: Plutonic - Inactive Volcanism, CV-3: Extensional Domain" is not in the list of possible values (CV-1a: Magmatic - Extrusive, CV-1b: Magmatic - Intrusive, CV-2a: Plutonic - Recent or Active Volcanism, CV-2b: Plutonic - Inactive Volcanism, CV-3: Extensional Domain, CD-1: Intracratonic Basin, CD-2: Orogenic Belt, CD-3: Crystalline Rock - Basement) for this property.


Geologic Features

Modern Geothermal Features: Blind Geothermal System [12]

Relict Geothermal Features:

Volcanic Age: No volcanism

Host Rock Age:

Host Rock Lithology: sandstone [13]

Cap Rock Age:

Cap Rock Lithology: shale [14]


The Heber geothermal area is located in California in the southern part of the Imperial Valley, a strike-slip region. The hydrothermal circulation is hosted within fractured sandstone units capped dominantly by shales.
